Hydraulic Burst Testing - Clark Testing

Hydraulic Burst Testing


A burst test is a type of test where the component is pressurized to a point where it can no longer contain the pressure and then fails catastrophically and bursts, releasing the pressure. A burst test can help determine the pressure at which a component will start to deform plastically or irreversibly. This information is very useful for engineers in designing parts and choosing materials. This testing can also help refine and validate FEA models and find flaws in manufacturing processes. Burst testing can determine the maximum pressure safety factor and help meet other quality and safety specifications.

Oftentimes during a product development cycle a DFMEA, or design failure modes and effects analysis will be performed to try to predict how a part will fail and what the effects will be, and for pressure systems a burst test can be the main method of validating those analyses.

Determining the burst pressure and failure mode can be important if a part is in an area that is exposed to other sensitive parts or to people, since a part that bursts can possibly send shrapnel flying which can cause even more damage. A burst pressure test can help determine and reduce these risks.
